We have a backup box (running Debian/Etch) with thirteen SATA disks connected to it: - four to the on-board controller - seven to an 8-port add-on controller - two to a 2-port add-on controller At reboot the Linux kernel inconsistently numbers "sda,b,c,...": it can start with either of these three. This is a major problem for us, which we are trying to fix. Besides, if we pull, say, the second drive from the 8-port card, then the drives 3-8 get renamed.
Is there a way to tie drive names to specific ports on specific controllers? Ideally, we want a system on which pulling one drive will not cause re-naming of all subsequent drives. I know that udev can match drive names to specific *drives*, but this will not work for us - we need to tie to ports on controllers, not serial numbers of drives. We tried making use of the /dev/disk/by-path/* symlinks, but those, too, seem to change from reboot to reboot. Here's the lspci output for our controllers: # lspci |grep -i ata 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) Serial ATA Storage Controller IDE (rev 01) 02:01.0 RAID bus controller: Silicon Image, Inc.
